5.5 Question 5 And Its Answers (A Continuation From Part 2)
Do you see evidence of suspicious activity? Identify 1- 10 locations where you believe the suspicious activity is occurring, and why. Please limit your response to 10 images and 500 words.
Suspicious Activities Can Be In The Following Forms:
Unknown locations not found on map
Gathering of two or more individuals at the same location at the same hour for extended periods
Individuals frequenting unusual places at abnormal hours
5.5.1 Presence of Anonymous Locations (Shown As Black Dots On Map)
These are locations where there were multiple instances of GPS points remaining stationary for more than 10 mins. These unknown locations do not conform to known locations on the furnished map pic.

5.5.2 Suspicious Monitoring Of Key Officials’ Homes (by Bodrogi, Vann, Osvaldo and Mies)
Showcasing only residential points, Bodrogi (ID: 15, black line), Vann (ID: 16, blue line), Osvaldo (ID:21, purple line) and Mies (ID:24, red line) were seen patroling key executives’ houses located near the centre area. (Hover over the lines and points to see the ID and owner of each residence)
It begs the question as to the main cause of Isande’s wayward driving. Though it’s highly unlikely that he veers from side to side throughout his drive, it suggests that his GPS device is either faulty or that it has been tampered to cover his tracks. Relooking at the places he visited, there is little to suggest that he might be a risky character. But nonetheless, his wayward movements remain suspicious.
5.5.4 Possible Suspicious Gathering At Kronos Capital On 18th and 19th Jan
On 18th Jan, Bodrogi (ID: 15, black line) met Nubarron (ID: 22, blue line) at Kronos Capital in the afternoon. This location was visited in the morning by Nubarron, as well as Vann (ID: 34, red line) in the evening. Herrero (ID:25, green line) was also stationary for approx. 24 hours in this location on 19th Jan.
